Frequently Asked Questions

Everything you need to know about editing PDF metadata with CedarPDF.

Is editing PDF metadata free?
CedarPDF is truly free. Unlike other online tools, it doesn't set daily usage limits or restrict PDF file size. It also doesn't require you to provide an email address or register. Furthermore, it doesn't secretly add watermarks to processed PDFs.
Does editing metadata change the content or quality of my PDF?
No. Editing metadata only updates the hidden document properties (like title and author). The actual text, images, layout, and quality of your PDF remain completely untouched.
What is the maximum size of PDF files I can process?
In fact, there is no hard limit to the file size, as long as your device has sufficient processing capacity. For current standard PCs or mobile phones, we recommend that the size of the PDF file to be processed should not exceed 200MB for optimal performance.
What happens if my PDF is encrypted or password-protected?
If your PDF has an "open" password (required to view the file), you won't be able to load it. If it has a "permissions" password, you may still be able to edit the metadata, but some features might be limited. Our tool will notify you with a warning if the PDF is encrypted.
How can I use this tool offline?
Although CedarPDF is an online PDF processing tool, you can still process PDF files offline. Simply open this webpage when you have internet access, and remember not to close the webpage or your browser. Then you can process PDF files offline.
Do I need to install any software or app?
Using CedarPDF doesn't require any software or app downloads. It allows you to select PDF documents and process them entirely within your device's web browser.
Can I use CedarPDF on devices other than desktop computers?
Of course! CedarPDF is designed to work on all types of devices (PC, Laptop, Mobile, Tablet) and operating systems (Windows, Mac, iOS, Android).
